T-Mobile beefed up its Wi-Fi capable BlackBerry portfolio today by announcing its BlackBerry Pearl 8120. Yes, we’re well aware that T-Mobile has had a BlackBerry Pearl of its own for quite some time, but the original didn’t have the HotSpot @Home support ($9.99 per month) that the increasingly popular BlackBerry Curve and 8830 handsets have.

RIM added an improved version of SureType, the auto-complete typing software, which now offers better word completion and a spell check. The new Pearl also sports a souped up 2MP camera; the original Pearl 8100 has a 1.3MP one. It also has increased media playback functionality and a 3.5mm headphone jack, similar to the Pearl 8130.

T-Mobile says the 8120 has an enhanced interface that offers visual improvements in everyday tasks like web browsing, e-mail, and calendar.
